Usually we warn people before banning them, and often many times, but sometimes an account has been breaking the site guidelines so badly and so frequently that we just ban them. When I scrolled through your comment history I saw so many cases of this that you fell into the latter category.

Example: https://news.ycombinator.com/item?id=37210786 - you can't post like that here, no matter how wrong someone is or you feel they are, and even a quick glance at the rules (https://news.ycombinator.com/newsguidelines.html) ought to have made that clear.

It doesn't have to be permanent, if you genuinely want to use HN as intended—that's what I tried to explain above.
